Abstract
Abstract A hose jacket of acetal resin and designed to bend a flexible hose approximately 90* is formed in two partial semitoroidal sections joined together at the outer radius by a flexible hinge portion of the resin. The sections have an annular cavity conforming approximately to the size and shape of the hose. Folding the sections around the hose and latching the arcuate edges together at each end and the middle bends the hose sharply without kinking or damaging the hose walls. Forces exerted on the jacket by the hose assist in maintaining the latch elements in engagement with each other.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
165 words
A jacket for flexible hose comprising arcuate jacket sections each having a cross section conforming approximately to corresponding portions of the hose, attaching means for pivotally attaching said jacket sections together along adjacent arcuate edges, said jacket sections being swingable about the attaching means to surround a portion of said hose, and latching means for holding the jacket sections around said hose, said latching means comprising a hook means formed on one jacket section near the end of the arcuate edge having said attaching means of one jacket section, and a tab means formed in a corresponding location on the other jacket section, said tab means fitting in said hook means when said jacket sections surround a hose, said tab means having an effective wall thickness greater than the effective wall thickness of said hook means so the presence of a hose within said jacket sections exerts a greater force on the tab means to hold the tab means in engagement with the hook means.
Claim 2
Dependent Claim
165 words
A jacket for flexible hose comprising arcuate jacket sections each having a cross section conforming approximately to corresponding portions of the hose, attaching means for pivotally attaching said jacket sections together along adjacent arcuate edges, said jacket sections being swingable about the attaching means to surround a portion of said hose, and latching means for holding the jacket sections around said hose, said latching means comprising a hook means formed on one jacket section near the end of the arcuate edge having said attaching means of one jacket section, and a tab means formed in a corresponding location on the other jacket section, said tab means fitting in said hook means when said jacket sections surround a hose, said tab means having an effective wall thickness greater than the effective wall thickness of said hook means so the presence of a hose within said jacket sections exerts a greater force on the tab means to hold the tab means in engagement with the hook means.
Claim 3
Dependent Claim
47 words
The jacket of claim 1 in which the jacket sections are curved into a partial toroidal shape surrounding a hose with the jacket sections bending the surrounded hose portion into a curve, said attaching means comprising a bendable section made of the material of the jacket sections.
Claim 4
Dependent Claim
21 words
The jacket of claim 2 in which the attaching means is located on the jacket sections walls having the larger radius.
Claim 5
Dependent Claim
19 words
The jacket of claim 3 comprising a hook means and tab means at each end of said jacket sections.
Claim 6
Dependent Claim
63 words
The jacket of claim 4 in which the latching means comprises an opening formed in one jacket section near the edge opposite the attaching means, and pins formed in a corresponding location Of the other jacket section, said pins having barbed ends that pass through the opening when the jacket sections surround a hose, said barbed ends retaining said pins in said opening.
Claim 7
Dependent Claim
23 words
The jacket of claim 3 in which the attaching means are located at the edges of the jacket sections having the larger radius.
Claim 8
Dependent Claim
63 words
The jacket of claim 1 in which the latching means comprises an opening formed in one jacket section near the edge opposite the attaching means, and pins formed in a corresponding location of the other jacket section, said pins having barbed ends that pass through the opening when the jacket sections surround a hose, said barbed ends retaining said pins in said opening.
Claim 9
Dependent Claim
103 words
The jacket of claim 2 in which each jacket section has a longer radius portion and a shorter radius portion and comprising a plurality of spaced ribs on the interior surfaces of each shorter radius portion, said ribs extending substantially perpendicular to the radius of said shorter radius portion, said ribs blending with the respective jacket section approximately 90* from the open side of the jacket section, the amount of projection of said ribs into the respective jacket section interior decreasing as rib location approaches the open ends of the section, said ribs increasing the curvature of a hose surrounded by said sections.
